IMPROVEMENT IN MACHINES FOR TRIMMING AND BURNISHING SHO E-SOLES.

Specification forming part of Letters Patent No. 140,601, dated July 8, 1873; application filed February 1:2, 1873.

To all whom it may concern:

Be it known that I, BENJAMINJ. TAYMAN, of the city of Philadelphia and State of Pennsylvania, have invented certain Improvements in Machines for Trimming and Burnishin g Shoe-Soles, of which the following is a specification:

My invention relates to the following particulars: The jack for holding and moving the shoe for the trimming and burnishing operations has on its disk, which is fast to the revolving and carrying shaft, a stop, which, in connection with a holding and releasing spring, holds the reciprocating slide of the jack in connection with the disk, so as to cause the former to be turned one-half around during the operation of the trimming around the edge of the heel and toe of the shoe-sole, the spring releasing the plate for the sliding motion of the same, for the action of the cutters while the edge of the sole is trimmed between the heel and toe. And the same movement in the jack applies to the burnishing of the edge of the sole, as just described in relation to the trimming. The cutter stock, which has a swivel movement in adaptation to trimming around the edge of the sole,.is held down to the latter by means of a spring connected with a partially rotating standard in a vertical socket of an adjustable rest. To this standard the rear end of a connecting-rod of the stock is pivoted. The journals of the burnisher are eccentric with the shaft for giving a reciprocating motion to the burnisher, in connection with a reversible rotary motion imparted to the same by means of a belt-connection with a series of pulleys, as hereinafter described, and crank-connection of the shaft, on which the last pulley is situated, with the driving-shaft; the said two shafts having their wrist-pins at unequal distances from the center of the shaft, so that a reversible motion is given to the intermediate shaft, and imparted therefrom through the belts and pulleys to the burnisher-shaft, whereby a more complete .burnishing is efiected than by an unbroken rotary motion of the burnisher. In order to give a positive reciprocating motion to the burnisher the belts have a fast connection with the pulleys, as hereinafter described. There is a scale arranged with the adjustable rest with which the swivel-head carrying the pulleys, above mentioned, is connected to provide for setting the burnisher to suit different lengths of shoes. And there is also a similar scale in arrangement with the adjustable rest to which the cutter-head is connected, for a like purpose.

Figure 1 is an end view of the improved machine. Fig. 2, Sheet N o. 2, is a plan view of the same. Fig. 3 is a rear elevation of the jack'partly in section at the line as as of Fig. 2, showing the jack and trimming device in co11- nection with the table-top A, the burnishing device being removed from the table. Figs. 4 and 5 are views at right angles to each other of the trimming device. Figs. 6 and 7 are like views of one of the swinging boxes 00.

Like letters in all the figures indicate the same parts.

A is the table-top, and B its frame. 0 is the standing-head, with which the drivingshaft D and the carrying-shaft D are connected. E is a disk, permanently connected with the inner end of the shaft D; and E, a disk with the rim of which the reciprocating slide F, which carries the shoe, is connected.

The construction and arrangement of these parts being essentially the same as in a former application of mine, which is passed for issue, a particular description thereof is not given here.

What is novel in this jack is only a device for changing the motions of the plate F, as follows: The inner edge of the rim a of the diskE has stops 7), against which the outer end of the radial slide G, on the rear side of the disk E, bears when a longitudinal part of the sole, fromheel to toe, or from toe to heel, has passed the cutter or burnisher, as the case may be, so as to make a connection of the 7 said carrying-slide, and cause a half revolution of the same until the heel or toe has passed the cutter or burnisher. When this takes place the disk E is locked by a pin, d, on the end of the spring H, shooting into one of the holes 0 c on the flat face of the rim a, whereby the carrying-slide F is prevented turning, and the horizontal guides e c, which are fast to the rim a, are brought into a horizontal position, so as to admit of a longitudinal movement of the carrying-slide to bring a part of the shoe sole between the toe and heel past the cutter or burnisher.

Z is a sleeve on a boss at the front of the head 0, which has a rim, 2, between which and the inner edge of the rim a the slide is held when it comes vertically under the carrying shaft, the rim .2: being cut away it is allowed to pass around the lower stop I).

For unlocking the rim (0 to admit of the rotary movement of the carrying-slide F, there is a cam, f, on the rear side of the disk E, which bears against the arm g of the spring II, and bears the latter outward from the rim to, so as to disengage the pin d from the hole 0, with which it is connected. The end of the pin resting against the side of the rim until the other hole 0, half-way around the rim, has reached the pin, it then shoots into the same, thereby locking the carrying-slide F for another longitudinal movement of the shoe, as above described. Thus the reciprocating and rotary movements are given the shoe in succession for both the trimming or burnishin g operations.

I is a slotted rest let into the cross-groove h of the tabletop A and secured by the screw 2'. It has at its rear end a socket, j, provided with the upright rod J, to which the rear end of the rod K is pivoted, the front end of the rod being connected with the socket of the casting L in connection with the cutter-head M.

The arrangement of the cutter-head so far is similar to that shown in the application referred to above. The cutter-head is held up in a convenientposition forbringing it to the shoe, and is susceptible of a free up-and-down movement in accommodation to the shoe-sole bythe spring N, fastened at its rear end to the upright rod j, the front end being connected with the jointed piece L, there being a hole in the elbow K of the spring, in which said piece has a free movement. 0 is the knife fortrimming the sole, and O the cutter for trimming the welt. P is a guide, which runs in the seam around the shoesole; and P, a supplemental guide, which is adjustable on the arm of the guide 1? by means of theslot K and screw 1, so as to regulate the cut of the knifeO, and prevent its cutting into the upper. Q is a scale fast to the tabletop A, for setting the rest I in adjusting the cutter-head in adaptation to different lengths of shoes. M is a head, which supports the shaft It of the burnisher S. The journals 00 of the shaft R are eccentric with the shaft and turn in the swinging boxes 00 00, so as to give a reciprocating movement to the burnisher for giving a more perfect finish to the work, the motion being similar to that of hand-burnishing. The head is connected with the vertical swivel-head T on the front end of the rod U, the rear end of the rod being connected with the horizontal swivel-head T, which connects with the vertical swivel-head T connected with the socket j of the rest I. The rest is adjustable in the cross-groove h in the tabletop A and fastened by the screw i. The adjustment of the rest, so as to bring the burnisher to suit different lengths of shoes, is regulated by the scale Q, seen more clearly in Fig. 2. V V are pulleys on the burnisher-shaf t It. They are connected by means of the belts W W with the pulleys V on the pivot-rod X of the swivel-heads T and T The pulley V is connected, by means of the belt W, with the pulley V on the intermediate shaft X. This shaft is connected with the driving-shaft Y by the connecting-rod n and wrist-pins 0 o of the said shafts.

A reversible motion is given to the pulley V by the wrist-pins 0 and 0 being at unequal distances from the centers of their shafts. This motion is consequently imparted to the pulleys V and V and from them to the pulleys V V on the burnisher-shaft It, so as to give a reversible rotary motion to the burnisher. The ends of the belts W are secured to the pulley V and the middle part to the pulley V And the rear ends of the belts W W are likewise fastened to the pulley V V, whereby a positive reversible rotary motion is imparted to the burnisher. The front ends of the belts W W must be so connected with the pulleys V V as to make the reversible rotary motion of the burnisher opposite to the reciprocating motion.

The head M is held at a convenient point of elevation for bringing the burnisher to the shoe by a lug, p, on the lower side of the swivelhead T resting on the lug p of the swivel-head T When the burnisher is raised up above the shoe for connection with sole for burnishin g the latter, it is pressed downward with sufficient force for burnishing by the spring N, the heel of the spring being secured to the front side of the swivel-head T and its resilient end to the lower end of the yoke q, whose upper end connects with the swivel-head T. The force of the spring is regulated by the set-screw r. The burnisher S has a bevel-flange, s, adjustable thereon to suit different thicknesses of soles. It is fastened in its adjusted position by means of the set-screw t. The inner head of the shoe-sole is formed by a lip and bead, which are solid on the burnisher S. The outer bead is formed by a small annular bead on the adjustable flange 8. By using this adj ustable flange in adaptation to different thicknesses of soles, the necessity of using a number of irons of different thicknesses is avoided.

I do not claim, broadly, the semi-rotating and reciprocating jack for giving such movements to boots and shoes but only the devices above named.

I claim as my invention- 1. The combination and arrangement of the slide G, spring H having a pin, d, and rim at having stops 1) b and holes 0 c for changing the motion of the carrying-plate F, substantially as described.

2. The combination of the spring N with theupright rod J and jointed piece L for holding the cutter-head in an elevated position, and holding it in connection with the shoe-sole, substantially as specified.

3. The arrangement of the scales Q and Q with the slotted rest I for regulating the adjustment of the cutter-head and burnisher to suit different lengths of shoes, substantially as described.

4. The combination of the spring N and yoke q with the swivel-heads T and T for pressing the burnisher down upon the shoesole, thus dispensing with hand pressure, the degree of pressure being regulated by the setsorew, substantially as described.

5. The eccentric journals as of the burnishershaft R, in combination with the swinging boxes :0 xfor giving a reciprocating movement to the burnisher, substantially as and for the purpose set forth.

6. The combination of the connecting-rod n, wrist-pins 0 and 0, shafts X and Y, pulleys V, V V and V and belts W and W, as arranged, to give a limited reversible rotary movement to the burnisher, substantially as set forth.
